Yes. OmieBox has three leak-proof compartments which can hold up to 1 teaspoon of liquid each. Wet foods (soup, yogurt, dressing) should go inside the thermos.

No, please do not place OmieBox in the microwave. Handwashing is best. The high heat & harsh detergents used in dishwashers can damage OmieBox. Gentle hand washing keeps your OmieBox in tip top shape!

• Use caution when handling hot contents. Hot contents can cause pressure to build within the thermos resulting in a release of hot steam. Open with care to avoid burns.
• Don’t over tighten the thermos lid.
• Don’t pack carbonated or fermented items inside the thermos.
• Don’t boil the thermos.
• Don’t put the OmieBox or its thermos inside the microwave (or any heat source)
• Do use extreme caution when opening a stuck thermos lid as the internal pressure might cause the lid to eject forcefully. Always point it away from people and pets to avoid injury.
• Don’t put OmieBox or any of its components in the dishwasher.

There are two silicon seals in your OmieBox. There is one large square seal that goes around the perimeter of the box. The other is a round O-ring that goes around your thermos lid. Both need to be removed daily for cleaning. Wash in warm soapy water and let dry completely. Without daily cleaning, silicon is highly prone to mold growth which is irreversible and requires the part to be completely replaced. No biggie, we all get busy and forget sometimes. Should mold grow, just come to our website to buy spare seals – we’ll keep plenty in stock for you.
